Also I'm thinking it's the 8ohm TC112 v2. The older 4ohm cab would be less extended in the lows and I believe has a different horn and waveguide and crossover? (someone correct me if I'm wrong here)
No, I think it seems to be the older 4 ohm TC112 (v1). He does refer to it being 4 ohm, not 8 ohm. He also picked it up secondhand at a time when I think the 8 ohm version was not yet in production...?
The new 8 ohm version is a beast in the lows. Huge.
